Concept

Introduction This section provides guidelines and a procedure for changing the range of discrete

(0x and 1x) and register (3x and 4x) references.

Guidelines When you change the range of discrete and register references, follow these

guidelines:

Adjust the range of discretes in increments of 16 (one word)

Adjust the range of registers in increments of 1 (one word)

The total number of register and discrete references cannot exceed the maximum

of state memory displayed at the top of the dialog.

A minimum configuration of 16 0x discretes, 16 1x discretes, one 3x register, and

one 4x register is required.
